Mushroom Cap Jellyfish

These photos were
taken off Cayo Costa State Park (La
Costa Island) in southwest Florida. They were sent in by H.
Tiner. Great photos of a Mushroom Cap Jelly. This jelly has no
tentacles, but does have some appendages under the bell with
brownish pigmentation. The bell is clear or translucent white and
can grow to 20 inches in diameter. In the first two photos, the
jelly is upside-down. The third photo shows the jelly from above,
floating in shallow water.
